Binding and Unbinding an EIP

After you create a Cluster instance, you can bind an EIP to it to allow external access. If later you want to prohibit external access, you can also unbind the EIP from the instance.

Precautions

  • Deleting a bound EIP does not mean that the EIP is unbound.
  • Before accessing a database, apply for an EIP on the VPC console. Then, add an inbound rule to allow the IP addresses or IP address ranges of ECSs. For details, see Configuring a Security Group.
  • In the cluster instance, only dds mongos can have an EIP bound. To change the EIP that has been bound to a node, you need to unbind it from the node first.

Binding an EIP

  1. Log in to the management console.
  2. Click in the upper left corner and select a region and a project.
  3. Click in the upper left corner of the page and choose Databases > Document Database Service.
  4. On the Instances page, click the cluster instance name.
  5. In the navigation pane on the left, choose Connections. Click the Public Connection tab. In the Basic Information area, locate the dds mongos node and click Bind EIP in the Operation column.
